Alex Reid, Christopher Maloney, Katie Hopkins - how many of these moments do you remember?

CELEBRITY Big Brother has thrown up some pretty memorable moments over the years, but one thing that makes the show such a hit with viewers is seeing famous faces completely change their perceptions over the course of the series.

While some, such as Eastenders star John Partridge, TOWIE’s Gemma Collins or Blue singer Lee Ryan, have changed those views for the worse, there have been a handful who have brought the public around and turned those deafening jeers into HUGE cheers.

How many of these do you remember?

ALEX REID

Alex Reid surprised everyone with how well he came across on the 7th series of Celebrity Big Brother. Katie Price’s ex-husband was booed heavily on his way into the house, and continually explained that he wanted to “hopefully change these boos into cheers” - and he managed it. He became very good friends with Dane Bowers and Vinnie Jones, who gave him the nickname Rocky, comparing him to the iconic Sylvester Stallone character.

Alex managed to win the public over and won the show with 65% of the final vote, the highest win rate on the show at that time. He left the house to deafening cheers, and the crowd even chanted “Rocky, Rocky” as he made his way to be interviewed by Davina McCall.

CHRISTOPHER MALONEY

Christopher Maloney is most recognised from his stint on The X Factor, in 2012. His first audition saw him receive a standing ovation from the judging panel, Louis Walsh, Gary Barlow, Tulisa and guest judge Geri Halliwell. The singer finished 3rd on the show, but was tormented by trolls during the series, and spent £60,000 on cosmetic surgery when the show ended.

He headed into the most recent series of CBB to huge boos from the public, but his bubbly personality made him a hit with housemates, and viewers seemed to enjoy him standing up to series villain, The Only Way Is Essex’s Gemma Collins. The former cruise ship singer was greeted with a chorus of cheers as he left the house 22 days later.

Katie Hopkins has spent the last few years growing her reputation as one of the most hated women in Britain. Her controversial views regularly become headline news, and she often finds herself trending on Twitter for her outspoken tweets. So when she headed into Celebrity Big Brother last February, the deafening boos she received weren’t surprising.

What WAS surprising, however, was her portrayal once inside the house. She didn’t take back any of her statements, but seemingly became more human, and she showed off a more vulnerable side to herself. Viewers were shocked to see her break down in tears on more than one occasion - and she even surprised herself by making the final 2, alongside Katie Price. Although she came second, she was cheered on her exit, which no one could have seen coming at the beginning of the show.

MEGAN MCKENNA

The CBB crowd were not impressed with Ex On The Beach star Megan’s entrance into the house, especially after she seemingly called out singer Ellie Goulding for an argument they’d previously had on Twitter.

The reality TV star was one of the most memorable housemates in this year’s CBB series, maybe even ever, as she argued with her fellow celebrities. One of her rants even saw Megan trending on Twitter as she kicked off at John for his two-faced behaviour. Viewers found her tantrums hilarious, and memes began spreading online. She was evicted soon after, and left the house to huge cheers.

AUSTIN ARMACOST

Austin walked into the Celebrity Big Brother 16 relatively unknown in the UK, but made viewers furious with his VT - in which he blasted the UK. The crowd let him know exactly how they felt - and they booed Marc Jacobs’ ex-boyfriend so heavily that host Emma Willis had to calm them down.

Once in the famous house, the reality TV star showed his caring side, and the public changed their mind as he shaved his head to make housemate Gail Porter feel better. His bromance with eventual winner James Hill also made Austin a hit with the UK crowds, who cheered him loudly on his exit.
